Abstract
The present disclosure relates to a control device and method for estimating a drivable space in a surrounding environment of a vehicle. In particular, the disclosure relates to a 'free space estimation' solution with reduced validation effort. The control device includes one or more processors adapted to obtain sensor data, determine a surface flatness MF and a surface texture MR of at least one portion of the surrounding environment by means of two independent algorithms, and defining a drivable space based on obtained values.
